Omaha hold 'em

The more common occurrence of counterfeiting in Omaha is when a person's best possible low hand, called the "nut low", is counterfeited. As an example, say Alice has A♠ 3♣ J♦ Q♦ while Bob holds A♣ 2♦ 9♦ J♠ and Carol holds 9♥ T♥ K♥ A♥. If the flop comes 6♥ 7♥ 8♥, Carol has a lock on the high hand with her 10-high straight flush

, but Alice and Bob are still competing for the low half of the pot. Bob holds an 8-7-6-2-A, ahead of Alice's 8-7-6-3-A. In fact, Bob currently holds the nut low hand; no one can have a better low hand.

However, if the turn card is 2♣, Alice and Bob's fortunes have changed. Alice now has the nut-low of 7-6-3-2-A, while Bob must still play the A-2 from his hand for a low of 8-7-6-2-A. The turn card did not make Bob's hand worse, but it did make Alice's hand better. Bob's only chance at the low pot now is if a 3 comes on the river, counterfeiting Alice's hand and giving both Alice and Bob a 7-6-3-2-A to split the low half of the pot. (If a 3 does come on the river, the nut low hand becomes A-4 to make 6-4-3-2-A.)

On the other hand, on a flop of 8-7-6, a hand containing A-2-3-4 is considered counterfeit-proof, because it currently is the nut low (8-7-6-2-A), and even if an A or a 2 arrives on the turn, it will remain the nut low (7-6-3-2-A) and will remain protected from counterfeiting on the river. A player with this type of protection can be bolder in betting.

Texas hold 'em

Counterfeiting in Texas hold 'em is similar to counterfeiting in Omaha, in that hands do not change value. Often Texas hold 'em counterfeiting is less likely to cause a player to lose an entire pot. On a flop of Q-J-T, a player holding A-K will have flopped an ace-high Broadway straight. If the turn card comes a king, the player with A-K will still have the same straight, but now so will a player with A-7, resulting in a tie. The A-K player's hand didn't get worse in rank, but it becomes less likely to win the entire pot.

Counterfeiting in Texas hold 'em more often leads to ties, like in the example above, but can also result in losses. For example, if the flop is J-T-9, K-Q is the best possible hand. But if the turn card is a queen, a player who held K-Q will now be counterfeited and able to lose to a player with A-K.

In common usage, the term counterfeiting is sometimes applied in a non-standard way to situations where hands do change value. If the flop is J-7-5, a player who has 7-5 would have two pair and be ahead of a player with pocket aces. Another jack on the turn or river, however, will make the first player's hand objectively stronger—from Sevens and Fives to Jacks and Sevens—but now behind the second player's Aces and Jacks, with the original pair of fives being counterfeited by the pair on the board.
